CORNER-LOCK FOR BEDS.

Application filed Merch 5,

,Tplall lwhom it may concern:

'a citizen of the United States, residing in New York city/New York, in the county or Bronx and State ot New York, have invented certain new and useful lniprorerneiits in Corner-Locks for Beds, of which the follow ing is a specification.

My present invention relates to un iniprovement in corner locks for tnkedmvn met-al framing and is more especially adapted for use in hed or spring mattress frames.

@ne of the objects of the present device is simplicity of strueture thereby ati'ording eeonomy in manufacture :ind nt the suine time to obtain n reliable structure and one 'which is proof against abuse which siieh cerner locks sustain in use.

1n the accompanying cli-wings, Figure 1, shows n fragmentary plan view of my device Fig. 2 is e side elevation of the same teken on the line l-l, Fig. l looking in the. direction of' the arrows, Fig. 3 is another plan View of my device slit ring modified use ,as n, spring mattress corner lock. Fig. l is a side elevation partly in sect-ion tnlien on the line BME. Fig. 3 looking in the direction of the nrrovvs. Fig. 5 is li perspective vier.v of the looking lug whit-h 'forms one of the parts of my invention, Fie. G is a perspeo tive view of a supporting hrnel'iet, rind Fig. 7 is a perspective vieiv ot nn :ingle tapering look 4plate therefor.

referring to Fris. l find i?, it .vill be noted that the corner posts E) .md G are slotted at Y, which slots are for the purpose of permittiiw' the introtlirthm into the tif-oe. of fr has!) lie end ol' the looking lug l).

By reterring to Fig. 'T3 it will. he noted that the supporting brochet ll is sohiestnntielly channel shaped and that one :,trm l() therefore is slightly eervol in order to eonl'orrn to the corner pos-.t trenini-1t which it rests. lt is obvious that if square or any other type of corner post is used the seid arm 1.0 can be shaped to conform thereto in order to nford intimate eontnet n ith the surface there of. The arm l2 is nent :it right ongles to the wall l2 and forms :i mums or nttneh- 'ment thereto oli supporting; :i om` hor lfl, or other forms of support. oy menns o' riv ets or bolts nhieh are nosed through the holes 15, 16, which shoivn in the side arm 12.

Thus the simple unitary structure is Aformed with the corner post hy the supporting bracket ,ll which is not intended to be removed once it is placed iii-position.

The ivall 13 of supporting bracket 1l is bent :xt n sli ght :ingle to the arm l0 thereof :is indicated in Fig. 2, :it 20 in order to forni nn opening at the upper end thereof vvhieh is slightly larger than at the loiver end.

Both endsof the hasp 8 are left square so that they are for the various corner posts and are of such dimensions thatthey also leave a clearance for the entry of the lug 22 of the corner lock 21, and support the same against looseness or rolling movement during use. he tapered seat 13 of the supporting bracket 11 isenough smaller in dimension so that when -the tapered arm 22 of the locking lug 2l is entered therein to a seat, there is a clearance g left therebetween as indicated in Fig. 2. This clearance provides for wear and permits of a rigid fit between the' two said elements at all times under condition of use. Were the lower face of the corner lock 2l permitted to rest upon the edge f (Fig. 2) of the supporting bracket l1, this rigid lit could not be maintained.

From the foregoing it is seen that my construction permits oi the usual takedown of the bed frame for shipment etc., as the side rails are removable at will, as is customary. However, my corner lock may also be used for obtaining an economical corner lock for permanently assembled frames as in Figs. 3 and 4 wherein is shown a modified use of my device as applied to a mattress frame for beds wherein the side bars of the mattress comprise two tubes 28 and 29 which have their respective ends 30 bent upwardly at right angles thereto, forming posts, and are slotted like corner posts 5 and 6, at their upturned ends 30. The procedure for assembling is the same as indicated for the construction shown in F ig. 1. The only variation in structure is that the struts 14 of Figs. 1 and 2 are left out entirely so that the non-rolling support for the arm 22 of the corner lock 21 is taken entirely by the square end of the curved face of the lug 8. Should it be desirable, a rectangular piece may be riveted against the wall 12 in order to form an extra support against the spring tension.

For spring mattress frames the top face of the corner lock 21 may be riveted to an angle rail 31 which is suitably drilled with holes e and f of sufficient number to permit the introduction and stretching of woven wireiabric or springs 32, or other suitable means used in forming the mattress fabric therefor.

Vvhilemy device as described in the foregoing is intended to be stamped out of sheet metal, with the e); tion of the lug 9, which is cast metal.r4 it is o ions that theI hasp-lilie portion might be formed integral with the sup])ortinfl lasciai il by utili/.in` the inateriel displaced te 'cm slot 1T, er if my eninterchangeable or reversible' lock for takedown frames, the combination with a post, of a channellshapedsupporting bracket, one lwing of said.
